To all whom it may concern:

' Be it known that I, -HERBERT 'ROLAND KINGMAN, a citizen of the UnitedStates, residing at Mount Vernon, inthe State of Illinois, have inventeda new and useful Im rovement in liluid-Gears, of which thefol owing is aspecification.

My invention relates particularly to transmission gears in which a fluidis employed to transmit motion from driving parts to'driven parts. I

My-primary object is to provide a car which-transmits power at variablespee to a driven member, from a drivingmember revolving at constantspeed, or which transmits power at a uniform speed to a driven memberfrom a driving member revolving at ciency, at the-same time capable ofbein constructed simply and substantially an perfectly balanced withreference to the r0 tatlng axis, so as to permit of revolving at a veryhigh rate of speed. i

The invention is illustrated in the accompanylng drawing inwhich Figure1 represents a plan'view, half of whlch is shown in section in a planepassing through the axis of rotation as R. S. Fig. 2; and Fig. 2represents an end elevation with half of the end cap E. removed, showingthe ends of the rotor vanes. Fig. 3, represents the end caps -E indetail, showing an end elevation and a sectional view on the line 12 ofsaid end elevation.

The gear consists of a fluid tight casing" containing on its insidecircumference a plurality-of slots or teeth 0, and attached to thedriven shaft, within which casing revolve a plurahty of im eller bladesor vanes C, attached to the riving shaft.

' B, Fig. 1 represents a driving shaft receiv ing its motion from anysource of ower and carrying theimpeller vanes C, an their hub T, keyedt0 the said shaft with the key Q, the'vanes being divided'into separatedivisions and strengthened by the rib W, the

whole forming the'rotor or driving member..

A, Fig. 1 represents the driven shaft attached rigidl to the end cap E,of the casing, by means of t e plinU. The casing, consisting of theshell 1), t e end ca s E together with the valves F, and the stu g'boxesH, forms with the shaft A,'-the driven member. The ends of the twoshafts A, -and B; are separated by a slight clearance-X.

T e casing consists of anannular shell or cylinder D, containing on itsinside circumference a number of slots or teeth out parallel to the axisof the cylinder similarto an internal gear. This constructionisrepresented at O-O Fig.- 2. This cylinder or shell is closed ateach'end by caps E, which caps contain double walls and which also formthe bearings for'the shafts. The inner walls Z, of the end caps E," aresupported at .intervals on-lugs Y, from the outer walls and areconstructed of such a size as to leave openings'around the hub and alsoaround the circumference, which openings form 'passages from the spacebetween the double walls to the interior of the cylinder or shell D.

Except for the space occupied by the supporting lugs Y,'the free space Gbetween the outer walls of the end caps and the inner walls Z', isunencumbered, as shown in Fig. 3, which shows the details of the endcaps E.

The passages at the circumference lie'adja-- controlled by anyconvenient wheel N. In-

the case of automatic control, these levers are attached to acentrifugal or inertia governor mounted on .the driven shaft. Thestufling box. ca s H, are for the (purpose of holding the pac 'ng aroundthe sli ing valves and shafts to prevent the fluid contained in thecasing from leaking out.

P, is a plug. in the casing bymeansof which it may be fille d.

The operation of the gear is as follows In the position of the valves F,as shown, half way 0 en, u on the revolution of the vanes C, t e fluidwith which the case is filled, is thrown by centrifugal force along thevanes as indicated b the arrows and out at a tangent to the circ e ofrotation of the ti s of the vanes, into the slots or teeth 0. Tileimpact of the moving fluid against the teeth causes the casing o revolveat a speed inversely proportions -to the power taken from the gear andapproaches the speed of the Vance at no loa After the impact with theteeth, the fluid flows out at either end of the slots, back between thewalls of the casing and is drawn in at the hub through the openingsbetween the lugs Y, to re eat the circuit as indicated by the arrows inig.

1. When the valves F, are caused to slidein along the shaft toward thehub and close the passages, the circulation of the fluid is stopped,none is thrown off from the tips of the vanes because the slots arefull, and the casing remains stationary while the vanes revolve. 1

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is 1. In a fluid gear, the combination of afluid tight casing, a rotor or moving part in said casing adapted torotate independent of said casing and forming a fluid circuit with saidcasing, a fluid, and means for causing, directing and controlling theflow of said fluid fromthe rotor or driving member to the casing ordriven member in their plane of rotation and tangential to thecircumference .or circle of rotation of the rotor substantially asdescribed.

2. In a fluid gear, the combination of a fluid tight casing, a rotor ormoving part in said casing adapted to rotate independent of said casing,forming a fluid circuit with said casing and having impeller blades orarms adapted to cause and direct the flow of the fluid from said rotorto said casing, the interior surface of the circumference of whichcasing contains a lurality of projections or teeth against whic thefluid is directed and vflui 3. In a fluid gear, the combination of athrown, in their plane of rotation and tangential to the circumferenceor circle of rotation of the rotor, and valves in the path of the flowor circulation of the fluid to control or reven};l the flow orcirculation of said at wi fluid tight casing, a rotor revoluble in saidcasing, slots or teeth on the interior surface of the circumference ofsaid casing, hollow chambers in'the faces of said casing and valvesbetween said chambers and the interior of said casing substantially asdescribed.

4. In a fluid gear, the combination of a fluid tight casing, a rotor orrevoluble part in said casing forming a fluid circuit with said casingand cylindrical valves operated alon the shafts for the purpose ofcontrolling the circulationof said fluid in said circuit substantiallyas described.

5. In a fluid gear, the combination of a fluid tight casing, a rotor orrevoluble part in said casing forming a fluid circuit with said casing,hollow chambers in the faces of a said casing and cylindrical valves insaid circuit and operated along or around the'shafts for the purpose ofcontrolling and regulating the circulation of said fluid insaid circuit.

In testimony whereof I have hereunto set my hand. I
